Didn't some of the early PDA phones use stylus (styli?). Maybe these weren't phones, I just remember my brother showing me that feature on his pda 8 years ago or so.

As far as stylus use I got the Note2 because of the stylus. I thought I would use it all of the time. Turns out I rarely used it. Not sure I would use it on the Passport but it does seem like a natural option for a device such as this.

if the stylus has enhanced usability and features built in, then I would welcome it I guess. My worry is, that most people I know that have used a stylus, they end up loosing it, even when it has special storage space on the phone itself like the note. So I am not a big fan of it.

The palms had stylus and was very hard to operate them back then without one, but not the case with the passport; only if it brought some big added value feature I would consider it (like notes taking storage and transfer ability or something of the like)

I had a Note 2 back in the day and have been using pennable tablets for quite awhile. A stylus on a screen this small, Wacom or not, seems really gimmicky to me. I could count the times on one hand that I used the Note 2's stylus, and it wasn't even for anything productive.

A 4.5" screen is still incredibly small to write comfortably on. It's like a big post it note. It just seems easier to type what you need on the PKB.

I currently use BlackBerry 's "Hand Stylus" for drawing on my Passport with amazing apps from "Autodesk" found in Google's play store, and it works great! Still I love the qwerty keyboard for all it offers.

Why not, I think it might indeed be an interesting idea. However I think the hype generated by the Note series is quite ironic: It seems like almost everybody was glad to finally getting rid of it the stylus once the iPhone appeared, others quickly followed, especially the new Android devices.
Now, a few years later, that infamous input method is finally back and it seems like more and more people want it.

Then there is the physical keyboard, an input method which was still rather famous even in some of the later Nokia polls, which silently disappeared without any cheers and people find it awkward it stays alive in an absolute minority of devices.

Unnecessary. Moving around and doing things on the Passport is fast enough as it is. To be honest, I had a Note 2 and 3 and I must have taken out the pen just once or twice on either device. The stylus tracking was poor and the Samsung S apps were crap.

The Passport for itself is already a great device both size-wise and performance-wise. Just enought for thumbs to scribble directly on an all touch surface, since I scribble via hand writing whenever I type Chinese characters. Ditch the stylus... How about a capacitive back casing?

A stylus would be great for business users because of the ability to accept signatures directly on the device, sign PDFs, jot down quick notes, etc.

My main portable computer is a Surface Pro which has a wacom pen/digitzer much like the Note devices. Taking notes, writing, and drawing on it is great (especially with OneNote), but I'd imagine the same experience on a smaller screen would be less enjoyable.

With that said, I'd love to have a pen to use on my PP that isn't a crappy capacitive one.
